Printing on multiple printers #138

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. trying to print on 3 printers and calling applet.isDoneFinding() and 
applet.isDonePrinting() in loops
2.
3.

What is the expected output? What do you see instead?
the expected output is that the receipts should get printed on three printers. 
what I get is that the applet and java crashes and I think this happens after 
the first applet.isDonePrinting(). And if I don't call these methods every 
thing is printed on the last printer found

What version of the product are you using? On what operating system?
I am using latest version of jzebra and on google chrome and java 7

Please provide any additional information below.
My code:
var applet = document.jzebra;
findPrinter("kitchen")
while(!applet.isDoneFinding()){}
print()
while(!applet.isDonePrinting()){}
findPrinter("bar")
while(!applet.isDoneFinding()){}
print()
while(!applet.isDonePrinting()){}
findPrinter("shisha")
while(!applet.isDoneFinding()){}
print()
while(!applet.isDonePrinting()){}

Am I doing something wrong. when should I exactly call the methods. is there 
another way to ensure that the printing happens correctly

There are warnings in the sample.html to NOT use the while() loops any longer.

This is how I would do it.  (Psuedocode, not tested).

var printers = new Array("office1", "office2", "office3");
var commands = new Array("^XA^FO100,100^BY7^BCN,100,Y,N,N^FD000000^FS^XZ", 
    "^XA^FO100,100^BY7^BCN,100,Y,N,N^FD000001^FS^XZ", 
    "^XA^FO100,100^BY7^BCN,100,Y,N,N^FD000002^FS^XZ")
var counter = 0;

// Find the printer (jzebra will initiate the rest of the commands)
function doPrint() {
    applet.findPrinter(printers[counter]);
}

// If found, send commands
function jzebraDoneFinding() {
    var e = applet.getException();
    if (e != null) {
        applet.print(commands[counter]);
    } else {
       alert("Error! " & e.getLocalizedMessage());
    }   
}

// Incriment counter, print again 
function jzebraDonePrinting() {
    counter++;
    if (counter < printers.length) {
        doPrint();
    } else {
        alert("Printing completed to " + printers.length + " printers!");
    }
}
